feat(deps): add curl installer for lazydocker and binary download for wakatime

lazydocker: prefer the official install_update_linux.sh curl script over
system PM. The same script handles updates, so fish-deps update re-runs it.

wakatime: replace pipx with a direct binary download from github releases.
Detects architecture (amd64/arm64/arm) via uname -m, downloads the zip,
extracts the binary to ~/.config/wakatime/wakatime, chmods it, and
symlinks it to ~/.local/bin/wakatime. fish-deps update re-downloads and
replaces the binary in place.

Both new specials are added to the preferred-method block so they appear
before the system PM and are the default when prompted.
